一种婴幼儿体温监测装置的研制

Development of Temperature Monitoring Device for Infant

目的:研制一种可以连续监测婴幼儿体温并具备高温报警功能的装置。方法:装置基于MSP430F435单片机研制,采用单片机自带的比较器,计数器与少量外围电路完成高精度体温的测量,同时数据存储于单片机自带的Flash。结果:该装置可实时显示温度监测值及异常报警,同时实现30d不间断测量。结论:该记录系统具有低成本、低功耗、小体积等特点,它为婴幼儿动态体温的医学监测研究提供了经济实用和便于推广的解决方案。

Objective To develop a continuous temperature monitoring device for the infant, with the function of high temperature alarm. Methods The comparator and counter of MSP430F435 SCM and some peripheral circuits was applied to high-precision temperature measurement, and then the data were stored in the flash of MSP430F435 SCM. Results The device could display realtime temperature and alarm in case of abnormal temperature, which made continuous monitoring of 30 days realized. Conclusion The device, being low-cost, low-power-consumption and low-volume, is worth popularizing for dynamic monitoring of infant temperature.
